ABSTRACT:
Accordingly, the present invention, in one embodiment, encompasses an apparatus for the fluidized catalytic cracking of a hydrocarbon feed comprising: a riser which is generally vertically positioned within a catalyst disengaging zone and which has a plurality of openings around the circumference of the riser at its discharge end. The openings in the riser have a vertical stub portion that extends tangentially outwardly from the riser and communicates with a first end of an upwardly sloping curvilinear tunnel that terminates at a second end. The second end of the tunnel opens into a tangential opening in the primary cyclone. The area of the opening of the first end of the tunnel is larger than the area of the opening of the second end of the tunnel.
